CROSS-REFERENCE TO RELATED APPLICATIONS

This application is the U.S. National Phase of PCT Appin. No. PCT/EP2021/054573, filed Mar. 24, 2020, which claims the benefit of German Patent Application No. 10 2020 101 900.7, filed Apr. 7, 2020, the entire disclosures of which are incorporated by reference herein.

TECHNICAL FIELD

The invention relates to a sanitary insert, in particular for insertion into a faucet outlet and/or into a water conduit, comprising at least one housing part with a receiving space, at least one insert screen which is inserted into the receiving space of the at least one housing part, and at least one splitter unit which is arranged upstream of the insert screen in a flow direction of the fluid.

BACKGROUND

Such sanitary inserts, especially jet regulators, are known, wherein the insert screens ensure a homogenization of the jet and/or an admixture of air.

Sanitary inserts of the type mentioned above are often still assembled at least partially by hand for various reasons, for example if machine-controlled automated assembly is not possible. Care must always be taken to ensure that the orientation of the insert screen relative to the housing part is correct. For example, the insert screens have flow-through openings that must be correctly oriented relative to the housing part and/or other insert screens to establish correct functionality of the insert. Correct orientation can sometimes be difficult or time-consuming in the event of manual assembly.

SUMMARY

The object is therefore to create a sanitary insert and a method for its production, wherein the assembly of the sanitary insert is simplified.

In accordance with the invention, this object is achieved by a sanitary insert having one or more of the features disclosed herein.

In particular, in accordance with the invention, a sanitary insert of the aforementioned type is proposed for achieving the object, which is characterized in that at least one orientation aid is formed on the at least one housing part, and in that at least one mating orientation aid corresponding to the orientation aid is formed on the at least one insert screen. This results in the advantage that a simpler and thus faster correct orientation of an insert screen relative to the at least one housing part is possible. Thus, the assembly can be simplified and accelerated overall.

Advantageous embodiments of the invention are described below, which alone or in combination with the features of other embodiments optionally may be combined together with the features noted above.

An orientation aid can be characterized, for example, by the fact that when performing a process of orienting the two components relative to each other, initially, i.e. in particular via a first orientation path, there is a larger (lateral) clearance between the components in order to capture the insert screen, wherein this (lateral) clearance is reduced in the further orientation process, i.e. in particular via a second orientation path. The orientation paths can refer here to the path along which the insert screen is inserted into the at least one housing part during the insertion process. Preferably, the orientation is a centering of the insert screen within the at least one housing part and/or transverse to an insertion direction.

According to an advantageous development, it can be provided that the insert comprises an outlet structure forming an outlet side of the sanitary insert. The outlet structure can, for example, be formed here by the at least one housing part or can be placed on the at least one housing part.

In order to be able to achieve a particularly simple assembly of the sanitary insert, it can be provided in accordance with a further advantageous embodiment that the at least one housing part comprises a first orientation aid and a second orientation aid, and that the at least one insert screen comprises, corresponding thereto, a first mating orientation aid and a second mating orientation aid. Thus, it is possible to orient the housing part and the at least one insert screen relative to each other by at least two, in particular at least two different types of orientation aids on the housing part and two matching mating orientation aids on the insert screen. This allows even faster and easier correct assembly of the components of the sanitary insert.

In order to be able to orient the at least one insert screen in a centered manner in the receiving space in correct orientation relative to the at least one housing part, the at least one orientation aid can be formed as a centering pin, which in particular has a non-circular cross section. Thus, the insertion of the insert screen into the receiving space can be facilitated. In particular, the centering pin can have a multiangular or polygonal, preferably a quadrangular, cross section. Thus, in addition to the centered orientation of the insert screen within the receiving space, it is also possible to set up an orientation of the insert screen correctly rotated about the axis of the centering pin relative to the housing part. Here, it can be provided that a plurality of orientations are possible, which can be defined, for example, by the number of sides of the centering pin. Thus, a centered orientation of the at least two components relative to each other is possible.

Alternatively or additionally, according to a further advantageous embodiment, it can be provided that the at least one orientation aid is formed at least on an inner side of a housing wall, in particular of the housing part. In particular, the at least one orientation aid can be at least one orientation aid running in the insertion direction of the at least one insert screen into the receiving space, preferably extending continuously in the insertion direction of the at least one insert screen into the receiving space. Thus, a circumferential orientation of the at least two components relative to each other is possible.

In order to be able to achieve a particularly good orientation of the at least two components relative to each other, it can be provided that the at least one mating orientation aid of the at least one insert screen is formed by a sleeve, in particular a sleeve formed in a centered manner on the insert screen, and/or on an outer circumference of the insert screen.

According to an advantageous development, it can be provided that the at least one orientation aid defines at least one guide track along which the at least one insert screen is slidably guided. Thus, besides the correct orientation during the initial assembly of the components, the at least one orientation aid can additionally also ensure that the at least one insert screen can be transferred to a correct end position within the receiving space without still being incorrectly twisted relative to the housing part.

According to a further advantageous embodiment, it can be provided that a plurality of orientation aids are formed on the at least one housing part. In particular, they can be formed as orientation aids running in the insertion direction of the at least one insert screen into the receiving space, preferably extending continuously in the insertion direction of the at least one insert screen into the receiving space.

In order to be able to establish a correct rotation-dependent orientation of the at least one insert screen more easily, it can be provided according to a further advantageous embodiment that the at least one insert screen has a toothed structure which corresponds to a mating toothed structure of the at least one housing part. In particular, the toothed structure can be a toothed structure projecting from an upper side and/or on a lower side, in particular in an edge region. In particular, the mating toothed structure can be a mating toothed structure formed in a bottom region of the receiving space. Thus, the interaction of the toothed structure and the mating toothed structure can better ensure that the components were actually correctly orientated relative to each other during assembly. In particular, it can thus be better recognized whether the components are in a correct end position, especially since otherwise it is not possible for the components to bear against each other over a large area and/or free spaces are formed between them in the event of incorrect assembly.

In order to be able to extend the functionality of the sanitary insert, it can be provided that the sanitary insert comprises at least two insert screens inserted into the receiving space.

According to a particularly advantageous development, it can be provided that a first insert screen comprises a toothed structure and a second insert screen comprises a mating toothed structure corresponding to the toothed structure in order to correctly orient the two insert screens relative to each other.

According to a further particularly advantageous embodiment, it can be provided that, by means of the interaction of the at least one orientation aid and the at least one mating orientation aid corresponding to the orientation aid, an anti-rotation device of the at least one insert screen relative to the at least one housing part and/or the outlet structure is established. Thus, the best-possible functionality can be ensured.

In order to simplify the insertion of the at least one insert screen into the receiving space, it can be provided according to a particularly advantageous embodiment that the at least one orientation aid is formed in such a way that it widens in cross section in the insertion direction of the insert screen into the receiving space.

Alternatively or additionally, it can be provided that a free end of the at least one orientation aid comprises an insertion aid. In particular, the insertion aid can be formed as a tip. Preferably, this is in order to be able to insert the at least one insert screen more easily into the receiving space in the correct insertion position by means of the insertion aid. Thus, the insert screen can first be placed on the tip with the mating orientation aid so that the insert screen is already arranged in a centered manner with respect to the housing part. Subsequently, further orientation can be performed by a centering pin or a circumferential orientation aid interacting with another or the mating orientation aid before the insert screen is transferred to its final position in the housing part.

According to a further advantageous embodiment, it can be provided that the splitter unit comprises at least one fixing element, wherein an anti-rotation device of the splitter unit relative to the at least one housing part is established by an interaction of the fixing element with the at least one orientation aid and/or an insertion aid, in particular the previously mentioned insertion aid. In addition, the anti-rotation device can also ensure that the splitter unit is correctly arranged relative to the at least one housing part.

According to a particularly advantageous embodiment, it can be provided that the at least one orientation aid is formed as a centering aid.

According to a further development, it can be provided that a diameter, in particular a maximum diameter, of the at least one orientation aid corresponds at most to the width of two diameters of a hole of the outlet structure.

In order to simplify a fitting of the at least one insert screen into the receiving space, in particular by not having to make a fit at two different points when the insert screen is initially inserted, it can be provided that a first orientation aid is formed longer than a second orientation aid. In this way, initial contact is initially made only between the first orientation aid and the insert screen before further orientation is carried out, for example likewise via the first orientation aid and/or via a second orientation aid.

It can be particularly advantageous if the at least one splitter unit is formed as a splitter plate with a plurality of passage openings, in particular uniformly distributed and/or equally sized passage openings.

According to an advantageous development, it can be provided that a screen is arranged upstream of the at least one splitter unit in the flow direction.

In accordance with the invention, the object stated at the outset is also achieved by a method for producing a sanitary insert according to the coordinated method claim. In particular, the method can be configured for producing a sanitary insert as described and/or claimed herein. Preferably, in accordance with the invention, a production method can be provided for solving the problem, wherein at least one insert screen is placed on a first orientation aid, in particular a first orientation aid formed as a centering pin, via a matching mating orientation aid, wherein the at least one insert screen is finely adjusted via a second mating orientation aid, in particular a second mating orientation aid formed on the outer circumference of the insert screen, with a second orientation aid, in particular an orientation aid formed on an inner side of a receiving space of a housing part, by inserting the insert screen into a receiving space up to a stop point within the receiving space. Thus, manual assembly of a sanitary insert can be greatly simplified and thus achieved in a shorter space of time.

DETAILED DESCRIPTION

FIGS. 1-11 show two variants of a sanitary insert denoted in its entirety in each case as 1. However, the invention is not limited to the examples shown in the Figures.

The sanitary inserts 1 are each formed for insertion into a faucet outlet and/or into a water conduit. For this purpose, for example, at least one coupling can be formed on an outer side of a housing part 2 and can be inserted into a corresponding mating coupling on the faucet outlet and/or on the water conduit.

The at least one housing part 2 comprises a receiving space 3, which is configured to allow at least one insert screen 4, 5 to be inserted or fitted therein. The at least one insert screen 4, 5 can have the function of uniformly separating a water jet impinging on the insert screen 4, 5 and/or improving an air admixture to the water jet via an aeration device.

The sanitary insert 1 further comprises a splitter unit 6 for splitting a water jet flowing to the insert 1 in the position of use into a plurality of individual jets. In the flow direction 7, the splitter unit 6 is located upstream of the at least one insert screen 4, 5, so that an inflowing water jet first hits the splitter unit 6 and only then the insert screen 4, 5.

The splitter unit 6 can be formed, for example, as a splitter plate which is placed on the housing part 2, in particular on an open side of the housing part 2.

In order to facilitate easier assembly of the individual components of the sanitary insert 1 by hand, the sanitary inserts 1 from FIGS. 1-11 each have at least one orientation aid 8, 9. The at least one orientation aid 8, 9 can, for example, be formed as part of the housing part 2 or arranged thereon.

A mating orientation aid 10, 11 matching the at least one orientation aid 8, 9 is formed and/or arranged on the at least one insert screen 4, 5.

The at least one orientation aid 8, 9 interacts with the at least one mating orientation aid 10, 11 in such a way that the at least one insert screen 4, 5 is correctly oriented when inserted into the receiving space 3 and/or in such a way that insertion, in particular up to an end position, is only possible in correct orientation relative to the housing part 2.

The sanitary insert 1 further comprises an outlet structure 12 that forms an outlet side 13 of the insert 1. Thus, water flowing through the insert 1 exits the insert 1 again at the outlet structure 12.

The variants shown in FIGS. 1-11 each have a first orientation aid 8 and a second orientation aid 9. The at least one insert screen 4, 5 has, corresponding thereto, a first mating orientation aid 10 and a second mating orientation aid 11. The formation of a plurality of orientation aids 8, 9 and mating orientation aids 10, 11 has the advantage that the at least one insert screen 4, 5 is fitted at different, in particular spaced-apart, locations during insertion into the receiving space 3. This facilitates insertion and can therefore be carried out more quickly.

The first orientation aid 8 can, for example, be formed as a centering pin 14. In particular, the centering pin 14 itself can lie approximately centrally within the receiving space 3. Thus, it is possible to insert the at least one insert screen 4, 5 in a centered manner in the receiving space 3. A first mating orientation aid 10 embodied as an opening is correspondingly formed on the insert screen 4, 5, and the centering pin 14 is inserted into said opening when the insert screen 4, 5 is inserted into the receiving space. The mating orientation aid 10 can be formed, for example, as a sleeve 19 that is part of or arranged on the insert screen 4, 5. The first mating orientation aid 10 can be formed in a centered manner on the at least one insert screen 4, 5.

The centering pin 14 can further be configured to also define a predetermined orientation of the insert screen 4, 5 in the direction of rotation. For this purpose, the centering pin 14 can, for example, have a non-circular cross section 15. The mating orientation aid 10 formed as an opening can have a shape corresponding to the cross section 15. Thus, the at least one insert screen 4, 5 must first be placed on the centering pin 14 and then rotated about the centering pin 14 until the non-circular cross section 15 can be inserted in an appropriately fitting manner into the opening. It can be provided, for example, that the centering pin 14 has a multiangular or polygonal, preferably a quadrangular, cross section 15. It can be provided here that a plurality of possible orientations, but in particular a limited number of orientations, can be established between the housing part 2 and the at least one insert screen 4, 5.

The variants shown in FIGS. 1-11 have a second orientation aid 9 formed at least on an inner side 16 of a housing wall 17 of the housing part 2. The second orientation aid 9 is formed as at least one guide structure running in the insertion direction 18 of the at least one insert screen 4, 5 into the receiving space 3.

The second mating orientation aid 11 is formed on the outer circumference of the at least one insert screen 4, 5 in a manner matching the second orientation aid 9. When the at least one insert screen 4, 5 is placed in the receiving space 3, the mating orientation aid 11 rests at least in part against the orientation aid 9 and/or can be guided along it when the insert screen 4, 5 is brought into its end position. The second orientation aid 9 and/or the second mating orientation aid 11 can be formed, for example, as a material recess and/or a material accumulation.

In the variants shown in FIGS. 1-11 , the second orientation aid 9 is at least partially formed as at least one guide track 21, preferably running from an access of the receiving space 3 to a bottom region 33, in particular running continuously. The guide track 21 can be formed, for example, by at least one rail which is formed on the inner side 16 of the housing wall 17 as part of the housing part 2 or is arranged thereon.

In order to correctly orient the at least one insert screen 4, 5 in the direction of rotation relative to the housing part 2 at least in one end position, the at least one insert screen 4, 5 has a toothed structure 22. The toothed structure 22 can be formed on an upper side 24 and/or on an underside 25, in particular in an edge region 26. In particular, the toothed structure 22 can be formed by a plurality of teeth of equal or different widths in the circumferential direction, which can be inserted into correspondingly shaped recesses of a mating toothed structure 23. The mating toothed structure 23 of the at least one housing part 2 can be formed, for example, in a bottom region 33 of the receiving space 3. Preferably, each insert screen 4, 5 can have a toothed structure 22 (see, for example, FIG. 8 ).

In variants of the insert 1, as in FIGS. 1-11 , which comprise a plurality of insert screens 4, 5, a or the mating toothed structure 23 can alternatively or additionally also be formed on a second insert screen 5. By the interaction of the at least one toothed structure 22 and the at least one mating toothed structure 23, the one or more insert screens 4, 5 can be correctly oriented relative to each other and/or to the housing part 2, at least in the direction of rotation. In the fully inserted position, it can be provided that the toothed structure 22 and the mating toothed structure 23 are largely or fully in surface contact with each other. Preferably, the toothed structure 22 and the mating toothed structure 23 are each formed in an edge region 26 of the at least one insert screen 4, 5 and/or of the bottom of the receiving space 3.

By the interaction of the at least one orientation aid 8, 9 and the at least one mating orientation aid 10, 11 corresponding to the orientation aid 8, 9, in the variants of FIGS. 1-11 an anti-rotation device of the at least one insert screen 4, 5 relative to the at least one housing part 2 and/or the outlet structure 12 is established in each case.

The at least one insert screen 4, 5 comprises a plurality of openings, which can be formed by meshes, for example. The correct orientation between the housing part 2 and the insert screen 4, 5 can thus also achieve a correct orientation of the holes 30 of the outlet structure 12 relative to the openings of the at least one insert screen 4, 5.

In order to be able to achieve even better retention of the at least one insert screen 4, 5 within the receiving space 3, the at least one orientation aid 8, 9 can be formed in such a way that it widens in cross section 15 in the insertion direction 18 of the insert screen 4, 5 into the receiving space 3.

A free or upper end of the at least one orientation aid 8, 9 has an insertion aid 27 in each of the sanitary inserts 1 from FIGS. 1-11 . The insertion aid 27 can be formed as a tip 28 which widens in the insertion direction 18. The insertion aid 27 makes it easier to insert the at least one insert screen 4, 5 into the receiving space 3 in the correct insertion position.

The splitter unit 6 has a plurality of fixing elements 29, which are formed on the underside and/or on the outer circumference of the splitter unit 6. Through an interaction of the fixing elements 29 with the at least one orientation aid 8, 9 and/or the insertion aid 27, an anti-rotation device of the splitter unit 6 relative to the at least one housing part 2 is established. In addition, the passage openings 31 of the splitter unit 6 are thus correctly oriented relative to the insert screens 4, 5 downstream in the flow direction 7 and/or relative to the housing part 2 and/or the outlet structure 12. The fixing elements 29 can, for example, be formed as material recesses and/or material accumulations. In particular, the fixing elements 29 can be wedge-shaped.

A diameter, in particular a maximum diameter, of the first orientation aid 8, in particular of the centering pin 14, corresponds at most to the width of two diameters of a hole 30 of the outlet structure 12.

In the inserts 1 shown in FIGS. 1-11 , a screen 32 is arranged upstream of the at least one splitter unit 6 in the flow direction 7.

The invention thus relates in particular to a sanitary insert 1, in particular for use in a faucet outlet and/or in a water conduit, comprising at least one housing part 2 which is open on one side and has a receiving space 3 which has access via the open side, at least one insert screen 4, 5, which is inserted into the receiving space 3 of the at least one housing part 2, at least one splitter unit 6 which is arranged upstream of the at least one insert screen 4, 5 in a flow direction 7 of the fluid, and at least one orientation aid 8, 9, wherein at least one mating orientation aid 10, 11 corresponding to the orientation aid 8, 9 is formed on the at least one insert screen 4, 5.
